Product details
Overview
TPS650532RGET from Texas Instruments is a 5-channel power management IC integrating two synchronous step-down converters (DCDC1: 1 A, DCDC2: 1 A) and three low-input-voltage LDOs (VLDO1: 400 mA, VLDO2/VLDO3: 200 mA each), designed for single-cell Li-Ion/Li-Polymer powered portable systems requiring I/O and core voltage rails with high efficiency and compact layout.
For engineers reviewing the TPS650532RGET datasheet, TPS650532RGET pinout, TPS650532RGET application, or TPS650532RGET equivalent, key selection considerations include its 2.25-MHz fixed-frequency PWM operation, 180° out-of-phase dual-DCDC architecture for reduced input ripple, externally adjustable output voltages, and integrated reset with 100-ms delay - all in a 4.0 mm × 4.0 mm VQFN-24 package.
Technical Context
The TPS650532RGET implements a voltage-mode PWM controller with input voltage feed-forward for fast line/load regulation, enabling use of small ceramic capacitors. Its dual DC-DC converters operate synchronized with 180° phase shift to minimize RMS input current and reduce required input capacitance.
Power Save Mode (PFM) automatically engages at light loads (IPFM_enter ≈ VIN/32 Ω), while forced PWM mode is selected by pulling MODE high. Each LDO features internal discharge resistors (350 Ω for VLDO1–VLDO3), 1% output accuracy in PWM mode, and dropout voltage ≤280 mV at full rated load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| DCDC1 Output Current | 1 A - supports I/O rail for processors, FPGAs, or interface ICs without external current boosting |
| DCDC2 Output Current | 1 A - delivers core voltage for OMAP™/low-power DSPs and application processors |
| Switching Frequency | 2.25 MHz ±10% - enables use of ≤2.2 µH inductors and 10–22 µF ceramic output capacitors |
| LDO1 Output Current | 400 mA - powers higher-current analog subsystems or memory interfaces |
| LDO2/LDO3 Output Current | 200 mA each - supplies low-noise bias for sensors, audio codecs, or RF front-ends |
| Quiescent Current | 32 µA typical (both DC-DCs active, no load, PFM mode) - extends battery life in standby |
| Output Voltage Accuracy | ±1% in PWM mode - ensures stable core/I/O voltage under dynamic load conditions |
Pinout & Package
VQFN-24 package (4.00 mm × 4.00 mm, 0.5 mm pitch) with exposed thermal pad (PowerPAD™) requiring solder connection to PCB ground plane for thermal performance and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB_DCDC1 (Pin 19) | Feedback input | Connects to resistor divider to set DCDC1 output between 0.6 V and VIN - enables precise I/O rail tuning |
| FB_DCDC2 (Pin 13) | Feedback input | Connects to resistor divider to set DCDC2 output between 0.6 V and VIN - supports configurable core voltage |
| EN_DCDC1 (Pin 20) | Enable input | Active-high control for DCDC1 - allows independent power sequencing of I/O rail |
| EN_DCDC2 (Pin 21) | Enable input | Active-high control for DCDC2 - enables staggered startup to limit inrush current |
| EN_LDO1 (Pin 22) | Enable input | Active-high control for 400-mA LDO - supports software-controlled bias for peripherals |
| EN_LDO2 (Pin 11) | Enable input | Active-high control for first 200-mA LDO - isolates noise-sensitive analog blocks |
| EN_LDO3 (Pin 12) | Enable input | Active-high control for second 200-mA LDO - enables independent power domains |
| L1 (Pin 17) | High-side switch node | Connects to inductor for DCDC1 - requires low-ESR ceramic capacitor and proper layout for EMI control |
| L2 (Pin 15) | High-side switch node | Connects to inductor for DCDC2 - 180° phase shift relative to L1 reduces input ripple current |
| RESET (Pin 10) | Open-drain reset output | Active-low with 100-ms delay - provides reliable system reset after power stabilization |
| MODE (Pin 23) | Mode select | Pull high for forced PWM (fixed frequency); pull low for automatic PFM/PWM transition - balances efficiency vs. noise |
| AGND (Pin 24) | Analog ground | Must be connected to PGND1, PGND2, and PowerPAD™ - critical for feedback stability and noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| 180° out-of-phase dual-DCDC operation | Reduces input RMS current by ~30%, allowing smaller 22-µF input capacitor instead of ≥47 µF |
| Integrated 100-ms reset generator | Eliminates need for external RC reset circuit - ensures deterministic boot timing after power-up |
| Internal LDO discharge resistors (350 Ω) | Forces rapid output discharge when disabled - prevents back-powering of downstream circuits |
| 2.25-MHz fixed-frequency PWM + PFM mode | Enables <1-mm² solution size per converter while maintaining >90% efficiency from 1 mA to 1 A load |
| Externally adjustable DC-DC outputs | Supports custom I/O/core voltages (0.6 V to VIN) using standard 1% resistor dividers - no factory programming needed |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-rail power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS650531RGET | LDO3 fixed at 1.2 V (vs. 1.5 V on TPS650532RGET); identical DC-DC specs and pinout | Suitable where 1.2-V auxiliary rail required instead of 1.5 V - no layout change needed | Select TPS650531RGET only if system design specifies 1.2-V LDO3; otherwise TPS650532RGET provides wider margin for 1.5-V logic |
| TPS65053RGET | DCDC2 rated at 0.6 A (vs. 1 A); LDO3 fixed at 1.3 V; same package and pinout | Lower core current capability limits use to sub-500-MHz processors or non-performance-critical cores | Choose TPS65053RGET only for cost-sensitive designs with ≤600-mA core loads; TPS650532RGET supports full 1-A peak demand |
Compared with TPS65053RGET and TPS650531RGET, the TPS650532RGET uniquely delivers 1-A DCDC2 output with 1.5-V LDO3 - making it the only variant in the family suitable for 1-A core loads requiring a 1.5-V auxiliary rail without external components.

FAQ
What is the maximum output current supported by DCDC2 in the TPS650532RGET?
The TPS650532RGET supports up to 1 A continuous output current from its DCDC2 converter, which is optimized for core voltage supply in application processors and DSPs. This rating is validated across the full operating temperature range (–40°C to 85°C) and input voltage range (2.5 V to 6 V), with thermal derating applied above 70°C ambient per the RθJA = 31.4°C/W specification.
Does the TPS650532RGET support externally adjustable output voltages for all DC-DC converters?
Yes, the TPS650532RGET supports externally adjustable output voltages for both DCDC1 and DCDC2 via FB_DCDC1 (Pin 19) and FB_DCDC2 (Pin 13), respectively. Each feedback pin accepts a resistor divider to set output between 0.6 V and the input voltage (VINDCDC1/2), enabling custom I/O and core rail voltages without factory programming.
What is the function of the MODE pin on the TPS650532RGET?
The MODE pin (Pin 23) on the TPS650532RGET selects between Power Save Mode (PFM at light loads, PWM at heavy loads) when pulled low, and forced fixed-frequency PWM operation when pulled high. Forced PWM eliminates frequency variation for EMI-sensitive applications, while PFM maximizes light-load efficiency down to 32 µA quiescent current.
How does the TPS650532RGET handle power sequencing between its multiple rails?
The TPS650532RGET provides independent enable inputs (EN_DCDC1, EN_DCDC2, EN_LDO1–EN_LDO3) allowing precise control of power-up/down order. For example, DCDC2 (core) can be enabled before DCDC1 (I/O), and LDOs can be sequenced after their respective DC-DC outputs stabilize - all managed via external GPIO or PMIC control logic without additional components.
What is the output voltage of VLDO3 on the TPS650532RGET, and is it adjustable?
The VLDO3 output on the TPS650532RGET is fixed at 1.5 V and is not adjustable. This differs from TPS65053 (1.3 V) and TPS650531 (1.2 V), making TPS650532RGET the only variant in the family offering a 1.5-V auxiliary LDO rail - suitable for interfacing with 1.5-V logic standards or specific sensor requirements.
